Countercurrent Spray Tower, FRP desulfurization Tower Fiberglass Denitrification tower

FRP desulfurization tower, also known as countercurrent spray tower, is a more commonly used wet desulfurization absorption tower. The flue gas enters from the lower part of the absorption tower, and the desulfurizing agent is sprayed into mist droplets through the upper nozzle. The flue gas is in reverse contact with the mist droplets. The flue gas flow rate in the tower is generally 2.5-4.0m/s, which can keep most of the droplets in In the suspended state, the general residence time of large droplets is 3-5s, and the small droplets are in a suspended state under certain conditions. A two-stage mist eliminator is installed at the outlet of the absorption tower to remove the droplets carried in the flue gas, and the flue gas flow rate is about 3m/s. The advantage of the spray tower is that there are few parts in the tower, the structure possibility is small, and the pressure loss is small. Countercurrent operation is conducive to full contact between the flue gas and the absorption liquid.

The working principle of the glass fiber reinforced plastic denitrification tower: after the smoke enters the equipment with the air, it is blown into the tower by the induced draft fan at the head. There is a new type of cooling system at the entrance of the glass fiber reinforced plastic denitrification tower, and the flue gas enters the interior after cooling, and then passes through the atomization technology. For denitration, the particles and impurities in the flue gas are reacted with moisture. After denitration, the gas will be sent to the bottom of the tower, and will be discharged from the tail of the equipment after collection timing
